Answer:

-10x² + 4xy - 2y²

Step-by-step explanation:

2x(x + y) - (4x + 2y)(3x - y)

= 2x² + 2xy - 12x² - 4xy + 6xy - 2y²

= 2x² - 12x² + 2xy - 4xy + 6xy - 2y²

= -10x² + 4xy - 2y²

Answer:

There are 3 prime factors for 375 (1,3,5)

Step-by-step explanation:

Prime factors are prime numbers meaning they can't be further divided by a whole number.

Answer:

Both numbers = 27

Step-by-step explanation:

( x + x + 49 + 25 + 42)/ 5 = 34          Multiply both sides by 5

(2x + 49 + 25 + 42) = 34*5 = 170     Combine the left

(2x + 116) = 170                                 Remove the brackets.

2x + 116 = 170                                   Subtract 116 from both sides

2x = 170 - 116

2x = 54                                             Divide by 2

x = 54/2

x = 27

Check

27 + 27 + 49 + 25 + 42

170 / 5 = 34

It does check out.

27 is right.

Answer:

21/20

Step-by-step explanation:

One way to look at it:

Convert 1.05 to a percentage so it's easier to see it as fraction out of 100

fraction x 100 = %

1.05 x 100 = 105%

105% means 105/100, and reducing the fraction gives 21/20.

21/20 = 1.05

Answer:

$330

Step-by-step explanation:

Answer:

1.) x = 150

2.) x = 8.5

Step-by-step explanation:

1.)

[tex]\frac{x}{5}+10=40\\\\\frac{x}{5}=30\\\\x=150[/tex]

2.)

[tex]4x-36=-2\\\\4x=34\\\\x=8.5[/tex]

Answer:

1. x = 150

2. x = 8.5

Step-by-step explanation:

1. x/5 + 10 = 40

Get x by itself and then solve for x.

First, subtract 10 from both sides

x/5 + 10 - 10 = 40 - 10

x/5 = 30

Then, multiply by 5 to get x by itself.

x/5 = 30

x/5 * 5 = 30 * 5

x = 150

2. 4x - 36 = -2

Get x by itself and then solve for x.

First, add 36 to both sides

4x - 36 + 36 = -2 + 36

4x = 34

Then, Divide each side by 4

4x/4 = 34/4

x = 8.5

Answer: 49714.04

Step-by-step explanation:

Answer:

49,714.04

Step-by-step explanation:

Move the decimal dot to 1 digit before it

497,140.4 => 49,714.04

Step-by-step explanation:

numbers

first = X

second = (x-10)

Third = 4(x-10)

x + (x-10) + 4(x-10) = 124

2x -10 + 4x-40 =124

6x - 50 = 124

6x = 124 + 50

6x = 174

x= 29

therefore the ;

first number = 29

second = (x-10) = 29-10 = 19

third= 4(x-10) = 4(29-10)= 76

Answer: y = (-1/2)x + 2

Concept:

When two lines are perpendicular to each other, their slopes are negative reciprocals.

The reciprocal of a number is 1 divided by the number.

In other words, it is the image opposite of a term.

Solve:

Given information

Given line = y = 2x - 5

Point = (-4, 4)

Find the slope of the line

Given the line is perpendicular to the line y = 2x - 5, the slope of the line would be negative reciprocal of the line y = 2x - 5.

Slope of line [y = 2x - 5] = 2

Slope of new line = (-1/2)

Find the y-intercept by substituting the given point

Equation of the new line: y = (-1/2)x + b

y = (-1/2)x + b

4 = (-1/2) (-4) + b

4 = 2 + b

4 - 2 = 2 + b - 2

b = 2

Finalize the equation of the line

Slope = -1/2

Y-intercept = 2

[tex]\boxed{y=-\frac{1}{2}x+2 }[/tex]

Answer:

15

Step-by-step explanation:

you can add the absolute value of -7 with 8 so it's 15

The length of AD on the number line is,

⇒ AD = 15

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

We have to given that;

Number line is shown in figure.

And, The point A is at - 7 on number line.

The point D is at 8 on number line.

Hence, We get;

The length of AD on the number line is,

⇒ AD = | - 7 - 8 |

⇒ AD = | - 15 |

⇒ AD = 15

Therefore, The length of AD on the number line is,

⇒ AD = 15 units

12 cups of sugar needed.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

for 14 lemons= 2 cups of sugar need.

for 1 lemon= 2/14 cups of sugar need.

Now, for 84 lemons

=84*2/14

=6*2

=12 cups of sugar need.

Hence, 12 cups of sugar needed.
